The S&P 500 jumped nearly 20% over the last twelve months. You probably see that number and assume the market is dangerously overpriced. That assumption is wrong. Stock valuations actually declined during this upward run. The index recently traded at a 22.1 price-to-earnings ratio. That is a noticeable drop from 23.7 at the same point last year.
Corporate profits are simply growing faster than share prices. The underlying math of the market holds up, and the second quarter of 2026 is setting a blistering pace. Earnings Scout founder Nick Raich expects 20% overall earnings growth for the current quarter. The historical average gain is just 6%.
The first batch of corporate scorecards confirms this trend. Out of the first 50 companies in the S&P 500 to report results by mid-July, 96% beat Wall Street estimates. These early reporters delivered 32.4% overall earnings growth, according to recent MarketWatch data covering S&P 500 price-to-earnings ratios and Q2 2026 earnings growth data. That translates directly into cash. If you own a broad index fund, your portfolio companies are making significantly more money per share today than they did in 2025.
Analysts hear the 1999 dot-com comparisons constantly. They flatly reject them. Today’s technology firms generate massive free cash flow. They rely on recurring revenue subscriptions rather than the speculative clicks that drove the late 1990s boom. Chipmakers like Nvidia and ASML validated this tech-sector strength with solid second-quarter results. Meanwhile, giants like Meta Platforms and Microsoft sit at the center of an ongoing debate regarding their artificial intelligence capital spending. They are spending heavily. But they are also earning heavily.
The optimism extends far beyond the current month. Analysts are upgrading their long-term forecasts. Global forward earnings growth estimates for 2026 are nearing 25%, according to Firstlinks analysis tracking global forward earnings growth estimates and long-term tech sector upgrades. This broad market acceleration completely bypasses the recovery metrics we saw after both the 2008 financial crisis and the COVID-19 pandemic. Third-quarter estimates are already moving higher too. Forward revisions for the quarter ending September 30 climbed 3.7% recently.
The upward momentum is holding firm.
Why Strong Free Cash Flow Separates 2026 From the 1999 Dot-Com Crash
It’s easy to look at Nvidia or Microsoft and worry about a sudden collapse. But the historical connection to 1999 falls apart when you look at corporate balance sheets. During the dot-com era, companies traded on theoretical eyeballs and non-existent profit models. In 2026, the S&P 500 is driven by companies that print actual cash. If a stock goes up 20%, but its cash profit goes up 30%, the stock actually became cheaper to own. That is the exact mathematical reality playing out right now.
Investors shouldn’t fear high stock prices. They should watch the earnings revisions. As long as those third-quarter estimates keep climbing above that 3.7% mark, the underlying math supports the rally.
